The sequence to hydrogenate coronene cations: A journey guided by magic numbers
The understanding of hydrogen attachment to carbonaceous surfaces is essential to a wide variety of research fields and technologies such as hydrogen storage for transportation, precise localization of hydrogen in electronic devices and the formation of cosmic H2. For coronene cations as prototypical Polycyclic Aromatic Hydrocarbon (PAH) molecules, the existence of magic numbers upon hydrogenat...
متن کاملInfrared spectroscopy of matrix-isolated polycyclic aromatic hydrocarbon cations. 2. The members of the thermodynamically most favorable series through coronene.
Gaseous, ionized polycyclic aromatic hydrocarbons (PAHs) are thought to be responsible for a very common family of interstellar infrared emission bands. Here the near- and mid-infrared spectra of the cations of the five most thermodynamically favored PAHs up to coronene:phenanthrene, pyrene, benzo[e]pyrene, benzo[ghi]perylene, and coronene, are presented to test this hypothesis. For those mol...
متن کاملDevelopment of photofragmentation- based diagnostics
Development of photofragmentation-based diagnostic concepts for studying H2O2, H2O, HO2 and O3 in three different measurement environments, i.e. a flow of vaporized H2O2/H2O, a premixed laminar methane/air flame and a plasma, produced by a gliding arc discharge, are reported in this thesis project. In addition, quantitative NO2 laser-induced fluorescence, LIF, measurements in a plasma generated...
متن کاملUltraviolet photofragmentation of biomolecular ions.
Mass spectrometric identification of all types of molecules relies on the observation and interpretation of ion fragmentation patterns. Peptides, proteins, carbohydrates, and nucleic acids that are often found as components of complex biological samples represent particularly important challenges. The most common strategies for fragmenting biomolecular ions include low- and high-energy collisio...
متن کاملPatterns of ring current in coronene isomers.
The ipsocentric pseudo-p model is used to predict maps of induced current density for isomeric variations of coronene in which the central hexagonal ring is surrounded by 5, 6, and 7-membered rings. All isomers in the set are predicted to support strong diatropic perimeter ring currents, thereby conforming to the magnetic criterion of aromaticity.
